VRRP does not work when mixing tagged and native VLAN

VRRP does not work when mixing tagged and native VLAN.


My setup is quite simple at the beginning, i have VRRP on VLAN working correctly :

Ether2

–VLAN-300

----VRRP-300


But if i add a VRRP interface on Ether2 like this :

Ether2

–VLAN-300

----VRRP-300

–VRRP-NATIVE


Then VRRP-NATIVE does not work. The two MT routers stay in master mode for this VRRP. and i loose connectivity on one of the two routers. Disabling VRRP-NATIVE interface on the first one restore connectivity on the second one.


The problem does occur even if i choose a different VRRP ID for VRRP-300 and VRRP-NATIVE.


How to solve this problem ? I can’t use another port, because i have only one port available on the switch to connect each Mikrotik boxes.
